Abstract
Fully packed trails on the square lattice are known to be described, in the long distance limit, by a collection of free non-compact bosons and symplectic fermions, and thus exhibit some properties reminiscent of Brownian motion, like vanishing fuseau exponents. We investigate in this paper the situation for their non-intersection exponents. Our approach is purely numerical, and based both on transfer matrix and Monte Carlo calculations. We find some evidence for non-intersection exponents given by CFT formulae similar to the Brownian case, albeit slightly different in their details.
